Performance Upgrades....Who does them around Mass or CT

Recommended Posts

Have a 2013 Silverado, looking for someone to do a cam swap and usual reprogramming items that go along with it, does anyone know reputable person in CT, MA or RI that does work on the 5.3?


I also have a 83 C10 with a mild 350 in it and looking for someone to do the same, ideally put a small supercharger in it.

Thanks, new to the group but lifetime chevy guy.
